METHOD AND APPARATUS FOR PBODUCIN G CORE-YARNS.

To alliwhom t may concern:

Be 1t known that I, WILLIAM E. CLOGHER,

a citizen of the United States, residing atl Mankato, in the county ofBlue Earth and State of'Minnesota, have invented certain new and usefulImprovements in Methods and Apparatus for Producing Core-Yarns, of whichthe following is a specification.

The invention relates to a method and apparatus for producing core yarn,and it has for its chief object the production of a core yarn thread ofnovel manufacture, in which the core consisting of two or more threadsrun together will be completely and more or less, evenly covered by awrapper, in such a way as to produce on completion of the process, asingle strand, the use of which in knitted or woven fabrics, willproduce greater strength, .wearingquality, and elasticity than can beproduced in fabrics made from yarns comprised only of a single core andwrapper instead of a multiple core.`

As my process applies particularly to the use of two or lnore threadsrun before the dotfer Yring for la core where only one has heretoforebeen employed, I will designate the core as a multiple core consistingof two or more threads, as desired.

Core yarns containing but a single core have been found unsatisfactory,due tothe fact that it was not possible to so completely and evenly wrapor incase the core in the wrapper so as to prevent the covering fromslipping and tearlng from the core, lresulting in causing bare spots inthe yarn and lack ofstrength and elasticity, and the attempt to twisttwo single core yarn threads together after wrapping each separately,made the. yarn so heavy and bulky that it was found limpossible toproducev a thread lof the required size that 'would run satisfactorilyand without great waste on machines making'v the finer knit or wovenfabrics. By my multiple core process, it is possible to roduce a moreevenly covered multiplev core thread, and when twisted wlll be ineifect, a two or more ply thread under a single cover or wrapper whichimparts a strength under the old single core process, resulting y in agreater saving 1n waste, and'when wool is used `for wrapper and cottonfor core, it is hard to distinguish from an all wool yarn.

My method ,or process of producing mulfinlamre yarn.' consists infeeding sepa Specification of Letters Patent.

rated core threads in sets of two orv more,

cores and Wrapper 'between the second set of rub rolls to 'eifect a morecomplete'covering of the multiple cores, and finally winding thecombined multiple yarn `on a suitable spool in single strands.

After each set'of multiple core ends passes the guide-eyes it passesunder the 'wipe roll and to the' rub roll or apron. Each set of multiplecore ends is combined with its companion set or group running parallelthereto, and the two sets of multiple cores are now combined as one, andincased as a whole by the roving or wrapper in one single strand.

In carrying-out my improved methods, I have provided the apparatusillustrated in the drawing, in which- Figure 1 is a front perspective;Fig. 2 is a vertical, longitudinal section, through the center; Fig. 3is a front lperspective ,showino` the apparatus adapted to carry out amodied 'form of the process. Fig. 4 isa vertical longitudinal sectionthrough the center of Fig. 3; and Fig. 5 is a detail of the doiier ringroll. A

Referring 'to the several views, the numeral 1 indicates the frame,which may be of any suitable lconstruction. ,Mounted upon the frame ateach end thereof, are brackets 2, 2 in which is journaled aspool i",lhaving the multiple core threads wound thereon, and secured to theframe, in the rear of the spool 3, is la rod 4 carrying a number ofguide-eyes 5 arrangedA thereon in sets or groups of ytwo or more. 'Inthe present instance the guides are shown arranged in sets of two orpairs.

Mounted in the sides of the framebelow the rod carrying the guide-eyesis a wipe roll 6, and to the rear of the wipe-roll is a doifer ring roll'7 provided with rings 8. Also mounted in the sides of the frame is aset will be rubbed together-withtherovirf or wrapper supplied by thefdojiifer 'rings as Aet set or series of rub-rolls or aprons 9, and

immediately below this set of rub rolls is a second set 10. Below thedoer roll 7 is a second doer lring roll 11 and in front of saiddoier-roll 1l is a second wipe roll 12, both doer-ring rolls bein drivenby-belts (not shown) from center s aft'in'roll13f' The apparatus asabove described, withV 'threads to do'er-rolls; supplying rovmgs to theexception of the arrangement of the guide-eyes is of usual construction,and no claim is herein made to the same.

The multiple cores pass from thespool 3 through the guide-eyes 5 to theupper doer. rolls, thence under Athe upperlwipefrolland between theapron rolls, thehe'adsof each set of multiple ends beingy fedf"in:separatel until they reach the apron rolls, wherefl they pass underthe" wipe-roll. In `passing between the apron rolls, each set or pair'of'` core-threadsfwill be rubbed` together with the roving wrappedbetween each combined ,set of core-threads, producing ajsingleyarnlthread containing a double or multiple core, being in efl'ect'jatwo v'orgmore ply thread with a single wrapper.;ffln:v order vto providea more -completefwrlapp'er or coverfor the ,'multiplellcore, fthe threadthus acted nponpasses from the'upper set of apronrolls to the lowerdojer, ring roll and under thejlower 'wipe-roll.' After being Suppliedwith more rovings orwrapper' :andfurther rubbed between thel apron`rolls,' the multiple yarn is vwound upon jack spool 15.

In Figs.. 3 and 4, the. apparatus isv arranged to increase theproduction of the multiple yarn, as will be plainly-r seeny by referenceto Fig. 4'. The multiplefeore yarn passes fromthe upper set of rub rollaprons directly to' a jack. spool 16* hicbl-it is A spool 17 is'providel Vecond-sup# ply of core 'and a rQdprfbar l.81.carrying,

guide-eyes 1,9 is arranged in .afsuitable position to permit themultipleY core `to pass through the guide-eyes,in,pairsl or sets asheretofore described. rlhesets v'otmultiple threads in` -separatedposition, pass' to the lower doer-rin'g roll, under the lower wipe-Aroll andvbetween the apron rubs to a jack spool 20 upon which themultiple, yarn after having lbeen incased with: the rovings supplied bythe lower, doer-ringjroll, is wound.

It will be noted that it` desired, a rod or bar 21, provided withguide-eyesv 22, -see Fi 1, may be employed to guide the multip e coreyarn as it comes from the upper masses' the core-threads ofeach set orgroup while in theirv separated ioondition, said rovings beingk suppliedparallel `with said corethreads, `and the rubbing each set or group vofenveloped Coret-breads together into a j single strand.

2. rlhe method of' producing multiple core-yarns, consisting guidingcoreithreads, in sets or groups of two or more separated threads, tododerfrolls; supplying rovings to the threads of each set or- 4groupwhile in their separated condition; rubbing each set or group'ofmultiplecorethread 'and rovings into asingle strand;

then passing the multip1ecore,single strand said single strand 'to morecompletely envelop or wrap the same. c

3. An apparatus for producing multiple core-yarns, having in combinationmeans for guiding core-threadsin sets or 'groups of two ormore separatedthreads; a' doer- .separated sets or groups, whereby thecorethreadsVare' guided in separated sets or groupsof two or more separatedthreads;

va do'er-roll; a wipe-apron'for supplying .rovings to the separatedcore-threads oitl Veach set or group, and two sets of rubaprons`, oneset for; receiving the rovings and superimposed core-threads'in'separated position, and the otherv set .for rubbing the roving-envelopedcore-threads together to forma single yarn having a'multiple' core.

In testimony whereof I affix my signature in presence of two witnesses.
